ID'ing common sprouts--probably a tree

One of the maples, and it's a seedling. Probably re maple knowing the area.

Definitely a maple of some variety. Many species reseed easily and will sprout with abandon. Got any mature maples in the vicinity? These are most likely its offspring.

I wouldn't know a maple tree if it fell on me. I'll see if I can spot a mature form of the leaf online and compare around the house. There are a few big trees on neighboring properties, only one on ours but they are everywhere.

Thanks to everyone for narrowing down the suspects.'

Sycamore has alternate branching. This seedling has opposite branching, hence cannot be a platens.

Pretty darn big cotyledons for such a miniscule Sycamore seed. And thank you :)

Well I'll be darned. :)

'Sycamore' is the common name (in Great Britain) for a type of maple (Acer pseudoplantanus). This 'sycamore' would indeed have opposite branching. You can occasionally find one of these 'sycamore' maples planted in the USA; my friend had one in the backyard of her house in town. (It took me a while to figure out what type of maple that one was.)

In North America, the common name 'sycamore' is applied to a plane tree (especially Platanus occidentalis).

And, to be thorough, the 'sycamore' mentioned in the Bible is actually a type of fig (Ficus sycamorus).

The original poster's sprouts were definitely some sort of maple (Acer sp.).

Yes of course!! How stupid of me...I knew this at some point! We actually see feral sycamore maples in NYC area from time to time. Thanks!
